Purpose:
The purpose of this lab was to verify conservation of energy through the relationship between force (F) and potential energy (U) of a magnet.
Materials:
-An air glider with an attached magnet
-An air track with a vacuum.
-A fixed magnet that would repel the glider's magnet
-A motion detector
-Claps and rods to maintain the motion detector in place
Short summary of lab:
First we had to find the force that would repel the air glider. We integrate this force and obtain the potential energy. We then do a test to graph F, U and the total work over time.
Process:
We did a free body diagram for the air glider while on an inclined air track and obtained a glider mass of 340 grams.
Therefore, the Force_magnet = (Mass_glider)gsin(pheta)
We then took measurements of the distance between the two magnets and the angle of the air track.
We found F(r) = 0.001074x^(-1.44), we then integrated F(r) to find U(r)
We found U(r) = 0.0024409091x^(-0.44)
Before beginning the experiment we needed a way for the motion detector to have the separation of the magnets at all times. We placed the glider at a distance away from the magnet. This distance was 22 cm which we measured with a ruler. With the motion detector, we got a distance of 64.53 cm between the detector and the glider. Therefore, the separation between the magnets would be the position measured by the detector minus 42.53 cm.
We then ran the experiment. We gave the glider an initial speed and let it get as close to the magnet before it would be repelled back. These are our calculated columns.
